The B5373 is a short road in northeast Wales. Originally unclassified, it gained its number in the late 1920s.
The road starts in Gresford on the B5445 (former A483) and heads north along a traffic-calmed road into the village centre, initially passing a recreation ground on the right. We pass the church (whose bells are one of the Seven Wonders of Wales) and pub then descend steeply out of the village to go under the Chester to Wrexham railway line then over the present A483 and the River Alyn.
After crossing a tributary we climb steeply back out of the valley and skirt the eastern edge of the village of Llay. After crossing the B5102 at traffic lights an industrial estate is passed. Although the road has been in sight of open fields for some time there are still some more houses to go before it becomes wholly rural - and even then only briefly. The road soon reaches the outskirts of Hope. It bears right to avoid descending into the Alyn valley but skirts the eastern edge of town to reach journey's end. The A550 comes in from the left and takes over the way ahead.
